ASoC: Set BQ parameters for some Dell models
There are some Dell SKUs that need to set the parameters of the
crossover filter (biquad). Each amplifier connects to one tweeter
speaker and one woofer speaker. We should control HPF/LPF to output the
proper frequency for the different speakers. If the codec driver got
the BQ parameters from the device property, it will apply these
parameters to the hardware.
